Nah, have them leave some engineer's there. Ozzy is right, an Infantry battlegroup (1 Battalion plus attachments), plus the Tigers and a flight or two of Hornets would replace the forces they are pulling out.
Would take us to ~1.5 Battlegroups plus engineer's, helicopters and fast jet detachments. From memory there is currently roughly half an infantry battalion or so over there, plus the SAS detachment, ATC detachment (at Kandahar airport), engineer's and chinook detachment.
Hang on....
We need
more forces there, not
less and certainly not only the
same amount as now. We don't want to be merely replacing the Dutch but rather building more forces there in order to achieve the objectives that are not currently being met. I am really talking about politically using the potential of us taking over the reins to ensure the Dutch public believes that allies are stepping up and therefore making them less hostile to a continued battlegroup presence beyond their stated deadline and possibly even using the need for this an excuse to solve a potentially sensitive East Timor forces presence issue.
